Using GrapheneOS makes you a terrorist now. I'm a terrorist.
I used GrapheneOS without a sim card for 4 months and the battery life was great. I put a sim card in, and since then (2 months) the battery dies twice as fast no matter which profile it's in, and dies faster even on airplane mode. I left it at 80% the other day and went out, came back 6 hours later and it was dead and red hot. Maybe it's just a dodgy phone, maybe it's not doing something on the less-trackable sim co…
might just be an older phone and older battery
